In GSM mainly using Panel type antennas but in the case of Microwave Antenna using Horn antennas.

Microwave anteenas propogate signal straghtly. So line of sight (LOS) is main issue in the case of Microwave antenna, it means that both antennas must be allign in face to face.

Microwave antennas are using for link between BTS but GSM antennas are directly link with customers. Antenna Gain also very much difference both cases.

Microwave antenna's are used to give link between towers in order to create and the maintain the link or channel for call.

Microwave communication is a line-of-sight communication. For communicating long distances(two persons comm. through mobile between INDIA and U.S.)we use microwave comm. in which signals are sent to a satellite and from there to the destination.In this purpose we use Microwave Antennas for transmitting or receiving.

Tagging Fixed Assets with Bar Codes:

Tracking assets is an important concern of every company, regardless of size. Corporate having large number of assets at diverse locations, verifying the assets manually becomes error prone and inefficient. The task of identifying and locating a specific asset can be difficult unless numbering is scientific, systematic, and up-to-date.

The purpose of tagging assets with barcode tag is to automate the whole process of asset verification. It also involves confirming the existence of asset and its location through hand held scanners that capture information from barcode labels.

Tagging the asset with a barcode can bring in efficiency by ensuring the following aspects of asset management:

•Automation in the verification process.

•Reduced time and efforts in asset verification significantly.

•Reliable and accurate verification. During manual physical verification, at times some assets might be verified twice and some assets might be missed totally, which is ruled out in case of Bar code verification.

•The process match each asset with respective asset ID allotted by the company in its accounting system such as SAP.

•Locating an asset becomes much simpler.

•Brings Consistency and Uniformity of systems and procedures at all locations.

With efficient asset tracking companies can reduce expenses through loss prevention and improved equipment maintenance. They also reduce new and unnecessary equipment purchases, and they can more accurately calculate taxes based on depreciation schedules.
